Nectarine tree, Summer Lion--Tree

ABSTRACT

A new and distinct variety of nectarine tree denominated varietally as &#34;Summer Lion--Three&#34; which is somewhat similar to the Red Lion Nectarine Tree (U.S. Plant Pat. No. 5,591) and the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794) with which it is most closely related but which is distinguished therefrom and characterized as to novelty by producing fruit which are mature for commercial harvesting approximately July 25 through August 5 in Fresno County, Calif. and which further produces fruit that has a large size, a yellow-colored firm flesh, and is freestone by nature.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of nectarine tree, hereinafter referred to as "Summer Lion--Three", and more particularly to such a nectarine tree which is somewhat similar in physical characteristics to the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794), and the Red Lion Nectarine Tree (U.S. Plant Pat. No. 5,591), from which it was derived as a progeny following the successful cross pollination of the two nectarine tree varieties noted above, but from which it is distinguished therefrom and characterized as to novelty in producing fruit which mature for commercial harvesting approximately July 25 through August 5 in the San Joaquin Valley of central California; the subject variety maturing approximately six weeks later than the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794) and approximately fifteen days earlier than the Red Lion Nectarine Tree (U.S. Plant Pat. No. 5,591); and which is otherwise distinguishable by producing fruit which have a dark, intense red skin coloration, and are large in size as compared with other nectarine cultivars maturing in approximately the same season.

A substantial portion of the applicants' professional lives has been devoted to the creation and marketing of new and distinct varieties of fruit trees. The instant variety resulted from such activities. In this regard, the applicants have regularly selected fruit trees having desirable characteristics and thereafter cross pollinated the selected fruit trees in an effort to produce progeny having improved characteristics. For example, in the creation of the instant variety of nectarine tree, an object of the present invention was to perpetuate the superior characteristics of the Red Lion Nectarine Tree (U.S. Plant Pat. No. 5,591) and the desirable characteristics of the May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794).

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The applicants cross pollinated a May Grand Nectarine Tree (U.S. Plant Pat. No. 2,794), and a Red Lion Nectarine Tree (U.S. Plant Pat. No. 5,591) in a test block which is situated on the applicant's ranch, the ranch being located at 11024 East Dinuba Avenue in Selma, Calif. in the County of Fresno, in early 1983. The resultant progeny were grown to a state sufficiently mature to determine that the characteristics were desirable. The instant variety was thereafter selected and asexually reproduced by the applicants by removing scion wood which was subsequently budded into test nectarine trees in the fall of 1984. This first asexual reproduction has been continually observed by the applicants and it has been determined that the characteristics of these offspring were identical to those of the original nectarine tree.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing is a color photograph of four mature fruit of the subject variety; a twig bearing typical leaves displaying the dorsal and ventral coloration thereof; two fruit showing their external coloration sufficiently mature for harvesting and shipment; and two fruit divided in the axial plane to illustrate the flesh coloration; along with two stones, all of the subject variety.

Shipping quality: Unknown, although the firm, crisp flesh at commercial maturity strongly indicates that the subject variety will have noteworthy shipping characteristics.

Although the new variety of nectarine tree possesses the described characteristics as a result of the growing conditions prevailing in the San Joaquin Valley of central California, it is to be understood that variations of the usual magnitude and characteristics incident to growing conditions, fertilization, pruning and pest control are to be expected. 

Having thus described and illustrated our new variety of nectarine tree, what we claim is:
 1. A new and distinct variety of nectarine tree to be denominated varietally as "Summer Lion--Three" substantially as illustrated and described and which is characterized principally as to novelty by its production of dark red fruit which are ripe for commercial harvesting approximately July 25 through August 5 in Selma, Calif., the fruit of the subject variety being further characterized as to novelty by having a large size, a superior shape, and being freestone by nature.
